Aspartate Metabolism-Driven Gut Microbiota Dynamics and RIP-Dependent Mitochondrial Function Counteract Oxidative Stress.

Aspartate (Asp) metabolism-mediated antioxidant functions have important implications for neonatal growth and intestinal health; however, the antioxidant mechanisms through which Asp regulates the gut microbiota and influences RIP activation remain elusive. This study reports that chronic oxidative stress disrupts gut microbiota and metabolite balance and that such imbalance is intricately tied to the perturbation of Asp metabolism. Under normal conditions, in vivo and in vitro studies reveal that exogenous Asp improves intestinal health by regulating epithelial cell proliferation, nutrient uptake, and apoptosis.

Microbial community structure and functional characteristics in a membrane bioreactor used for real rural wastewater treatment.

Electrocatalysis: From Planar Surfaces to Nanostructured Interfaces.

The reactions critical for the energy transition center on the chemistry of hydrogen, oxygen, carbon, and the heterogeneous catalyst surfaces that make up electrochemical energy conversion systems. Together, the surface-adsorbate interactions constitute the electrochemical interphase and define reaction kinetics of many clean energy technologies. Practical devices introduce high levels of complexity where surface roughness, structure, composition, and morphology combine with electrolyte, pH, diffusion, and system level limitations to challenge our ability to deconvolute underlying phenomena.

investigation of human salivary microbial growth with lysogeny broth for translational research-A pilot study.

However, failed clinical trials often lead to wastes of resources, indicating a need for preclinical models. In this pilot study, we aimed to compare the salivary microbiome by metagenomics analysis before and after lysogeny broth culture for prospective translational studies.

Boosting the oxygen reduction activity on metal surfaces by fine-tuning interfacial water with midinfrared stimulation.

Heterogeneous catalysis at the metal surface generally involves the transport of molecules through the interfacial water layer to access the surface, which is a rate-determining step at the nanoscale. In this study, taking the oxygen reduction reaction on a metal electrode in aqueous solution as an example, using accurate molecular dynamic simulations, we propose a novel long-range regulation strategy in which midinfrared stimulation (MIRS) with a frequency of approximately 1,000 cm is applied to nonthermally induce the structural transition of interfacial water from an ordered to disordered state, facilitating the access of oxygen molecules to metal surfaces at room temperature and increasing the oxygen reduction activity 50-fold. Impressively, the theoretical prediction is confirmed by the experimental observation of a significant discharge voltage increase in zinc-air batteries under MIRS.

Decreasing the aggregation of photosensitizers to facilitate energy transfer for improved photodynamic therapy.

The mode of energy transfer between photosensitizers and oxygen determines the yield of singlet oxygen (O), crucial for photodynamic therapy (PDT). However, the aggregation of photosensitizers promotes electron transfer while inhibiting pure energy transfer, resulting in the generation of the hypotoxic superoxide anion (O) and consumption of substantial oxygen. Herein, we achieve the reduction of the aggregation of photosensitizers to inhibit electron transfer through classical chemical crosslinking, thereby boosting the production of O.

Incorporating Indium Oxide into Microplasma Reactor for CO Conversion to Methanol.

The clean conversion of CO is a strategic issue for addressing global climate change and advancing energy transformation. While the current clean CO conversion is limited to the H pyrolysis process, using HO as a proton source is more promising and sustainable. A microplasma discharge method is developed, driven by electricity, and utilized for CO conversion with HO.

Impact of Dexamethasone on Blood Glucose After Total Knee Arthroplasty in Patients With Type 2 Diabetes.

Objective: With the global aging population, the incidence of OA is rising annually, and the number of TKA surgeries is rapidly increasing, placing a heavy economic and healthcare burden on society. As one of the key medications in the ERAS protocol, DXM can significantly reduce postoperative pain, suppress nausea and vomiting, and accelerate patient recovery. However, the safety of perioperative DXM use in patients with diabetes remains unclear.

Solventless Dual-Cure Liquid Resins Via Circular Use of Phthalic Anhydride for Recyclable Composite Applications.

Fiber-reinforced composites (FRCs) possess a remarkable strength-to-weight ratio, making them ideal light-weighing alternative materials of metals used in automotive, aerospace, and outdoor equipment applications, but their recycling is challenging. Chemically recyclable thermoset polymers can enable fiber recovery and reuse; however, challenges remain in the separation and purification of depolymerized small molecules for efficient polymer recycling. To this end, a series of liquid resins for chemically recyclable polymer networks is designed based on phthalic anhydride, a widely produced and inexpensive chemical.

Research progress in diagnosis and treatment of psychogenic pseudosyncope in children.

Psychogenic pseudosyncope is one of the primary causes of transient loss of consciousness in children and adolescents, essentially classified as a conversion disorder that significantly impacts patients' quality of life. Clinically, psychogenic pseudosyncope shares certain similarities with vasovagal syncope in terms of pre-syncope symptoms and triggers, making it sometimes difficult to differentiate and easily misdiagnosed. Therefore, placing emphasis upon the characteristics of psychogenic pseudosyncope is crucial for early identification and treatment, which holds significant importance for the mental and psychological health of children and adolescents.
